Introduction to Year 12 Physics
If there is no air between Earth and Mars what does
the rocket push against to get to Mars?
If almost all of the fuel is used to escape the Earth’s
gravity, how can the rocket make all the way to Mars?
How do they calculate the orbits around Earth and
Mars?
What keeps a satellite in orbit? What is
weightlessness?
How can they work out how much force is required to
slow the capsule down in 7 minutes? What is 7g?
What alternatives can be used to power a space craft?

Introduction to Year 12 Physics
Energy
The curriculum statement assumes that the student has had a
thorough introduction to the concept of energy and its
conservation. Specifically, students should be familiar with the
expressions for work (including examples in which the force is at
an arbitrary angle to the displacement), kinetic energy, and
gravitational potential energy. Energy conservation should have
been considered using as large a number of practical situations
as possible. Students should understand and be able to
distinguish between elastic and inelastic collisions.

It is most important that you recognise that
if students work cooperatively as a group,
learning from one another, then they should
all perform better in the final examination
and your school based marks will be
moderated upwards. This cooperation
makes the learning good fun and they will
all benefit.
